Objective:To examine the interaction between gender and the visceral adiposity index (VAI) in relation to the risk of type 2 diabetes mellitus (T2DM).Methods:This retrospective cohort study utilized data from the public Dryad database derived from the NAGALA (NAFLD in the Gifu Area, Longitudinal Analysis) project (1994-2016). Participants were stratified into quartiles based on VAI levels. A multivariate Cox proportional hazards regression model was employed to evaluate whether VAI independently predicts T2DM risk. Kaplan-Meier survival curves and receiver operating characteristic (ROC) curves were constructed for each VAI quartile. Subgroup analyses were conducted to examine associations across age and body mass index categories. Both multiplicative and additive interaction effects between gender and VAI were assessed. Additionally, gender-specific Cox models were fitted to further explore these associations.Results:A total of 15 453 participants [8 419 males and 7 034 females; mean age, (43.7±8.9) years] were included, with a median follow-up duration of 5.39 years. During follow-up, 373 participants (2.4%) developed T2DM. After adjustment for potential confounders, higher VAI levels were independently associated with increased T2DM risk ( HR=1.16; 95% CI 1.11-1.21), consistent with the results across VAI quartiles. Kaplan-Meier analysis revealed a significant trend of increasing T2DM incidence across VAI quartiles ( P<0.001). The area under the ROC curve for VAI in predicting T2DM at 3, 5, and 10 years was 0.755, 0.735, and 0.696, respectively. Sensitivity analyses showed that elevated VAI was associated with increased T2DM risk across all age and body mass index subgroups (all P<0.05). Regarding interaction analysis, the HR (95% CI) for the multiplicative interaction between VAI and gender was 1.22 (1.19-1.26). The relative excess risk of interaction was -1.08 (95% CI -2.96 to -0.06), the attributable proportion of interaction was -0.54 (95% CI -1.35 to -0.01), and the synergy index was 0.48 (95% CI 0.26-0.91), indicating a negative additive interaction. Using low-VAI women as the reference group, the risk of T2DM in high-VAI women was higher ( HR=2.53, 95% CI 1.59-4.02) compared to high-VAI men ( HR=2.01, 95% CI 1.49-2.72). In gender-specific analyses, increasing VAI remained significantly associated with elevated T2DM risk after adjustment in both females ( HR=1.43, 95% CI 1.21-1.68) and males ( HR=1.16; 95% CI 1.11-1.22), with consistent findings across VAI quartiles. Conclusions:VAI and gender demonstrated multiplicative and additive interaction in relation to T2DM risk. The association between increasing VAI and T2DM risk was more pronounced in women than in men.

Objective:To analyze the risk factors of anxiety and depression in prostate cancer patients after castration, and establish a risk prediction model.Methods:A retrospective analysis was conducted on the data of 60 prostate cancer patients treated in Xi′an People′s Hospital from January 2019 to January 2022. The patients were divided into a training group ( n=42) and a validation group ( n=18) at a ratio of 7∶3. The patients received surgical castration and medical castration. One month after castration, the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were used to evaluate the anxiety symptoms and depression levels of the patients, respectively. Univariate and multivariate logistic regression analyses were used to identify the risk factors for negative emotions in prostate cancer patients after castration, and a risk prediction model was established. Results:In the training group, 19 patients had a SAS score ≥50, and 21 patients had an SDS score ≥50. Based on these scores, the training group was divided into a negative emotion group ( n=19) and an emotional stability group ( n=23). Multivariate logistic regression analysis showed that marital status, castration scheme, and postoperative Visual Analogue Scale (VAS) score were independent influencing factors for negative emotions in prostate cancer patients after castration ( OR=3.589, 3.364, 5.912, all P<0.05). In both the training group and the validation group, the risk scores of patients with negative emotions were significantly higher than those with emotional stability. In the training group, the area under the curve (AUC) of the risk prediction model for predicting negative emotions was 0.747, with a specificity of 71.02% and a sensitivity of 66.11%; in the validation group, the AUC, specificity, and sensitivity were 0.761, 66.59%, and 76.21%, respectively. The Hosmer-Lemeshow test showed that χ 2 was 4.285 6, P value was 0.830, and the c-index was 0.773(0.692-0.854). The calibration curve showed that the predicted curve was basically consistent with the actual curve, indicating that the prediction model had good discriminative ability and accuracy. Decision curve analysis showed that the model had high clinical significance. Conclusions:Marital status, castration scheme, and postoperative VAS score are important factors affecting anxiety and depression in prostate cancer patients after castration, and the regression model can successfully predict the risk of negative emotions.

With the development of society,the incidence of obesity has increased year by year in recent years,which has seriously jeopardized public health and safety,and has been a hot spot in the field of endocrine research.At the same time,obesity is also an important cause of a variety of metabolic diseases,such as metabolic syndrome,pre-diabetes,hypertension and polycystic ovary syndrome and other diseases,but the etiology and mechanism of obesity have not been completely clear,and basic research on obesity of traditional Chinese and western medicine still needs to be widely carried out.In this paper,animal models of obesity and its complications will be comprehensively summarized,and the model principles will be elaborated in combination with TCM syndromes and western medicine mechanisms,and evaluate their merits and demerits,so as to provide references for the selection of reasonable animal models for relevant experimental studies of obesity.

Objective:To explore the applied effectiveness of the Skin and/or tissue,Education,Cooperation,Understanding,Report and Evaluate (SECURE) nursing pathway based on action research method in the prevention process of medical device-related pressure injuries (MDRPI) of patients in the Intensive Care Unit (ICU). Methods:The SECURE nursing pathway based on action research method included the establishment of a skin care team to identify problems,and the formulation of conducting intervention plan,and the development of targeting nursing interventions to prevent the occurrence of MDRPI. A total of 84 patients hospitalized in the ICU of Hebei General Hospital from March 2022 to March 2023 were selected,and they were randomly divided into a control group and an observation group,with 42 patients in each group. The control group implemented routine method to prevent MDRPI during ICU treatment,while the observation group implemented SECURE nursing pathway based on action research method to conduct prevention. The MDRPI incidence,the quality scores of ICU nursing,the scores of the Short Form Health Survey-36 (SF-36) of patients,the assessment of the improvement of MDRPI patients,and the satisfaction of patients for nursing care were compared between the two groups. Results:The MDRPI incidence during ICU treatment in the observation group was 4.76％ (2/42),which was significantly lower than that in the control group,with a statistically significant difference (x2=11.052,P<0.05). The average scores for device usage,prevention assessment,positioning management and preventive nursing after nursing intervention in the observation group were respectively (88.45±2.05),(89.36±2.11),(89.25±2.15) and (91.45±2.25),all of which were significantly higher than those in the control group,with statistically significant differences (t=11.425,12.052,10.052,13.478,P<0.05). After nursing intervention,the average scores for physical function,social function,psychological function and material life as the SF-36 scale in the observation group were (85.47±2.05),(86.48±2.05),(88.46±2.15) and (90.25±2.44),respectively,which were respectively higher than those in the control group,with statistically significant differences (t=12.414,11.045,10.252,10.478,P<0.05). The occurrence time,improvement time of wound and ICU treatment time of presenting MDRPI patients in the observation group were respectively (4.05±0.54) days,(3.45±0.15) days,and (8.12±2.14) days. Compared to the control group,the occurrence time of the observation group was longer,while both the improvement time of wound and ICU treatment time of the observation group were shorter,with statistically significant differences (t=8.485,10.012,13.001,P<0.05). The satisfaction degree of nursing care of patients in the observation group was 95.24％ (40/42),which was significantly higher than that in the control group (x2=12.054,P<0.05). Conclusion:The SECURE nursing pathway based on action research method,which prevents MDRPI of ICU patients,can reduce the MDRPI incidence rate of ICU patients,and enhance the work quality of nursing care for MDRPI. It is helpful to the recovery of ICU patients,which can also shorten the treatment time of ICU patients.
